How are obsolete products handled?

Whenever possible, we will announce products that are being made obsolete with a 3-month Last-Time-Buy (LTB) window - effectively 3 month's notice before a product is made obsolete.

If stock still remains after those three months, the remaining product may still be available for sale for a little while longer (depending on the volume left and the reason for obsolescence).

There are some instances where a product may be given a shorter LTB period - or may have no LTB at all. This will usually be because a product has not sold for a very long time, and an LTB opportunity is unnecessary. However, there may be occasions where no LTB is given due to exceptional circumstances.


When a product is made obsolete, we will send an Obsolescence Notification to all authorized distributors, and to those who have registered for notifications directly from us. You can register for notifications on our Product Change Notification form. Please note, we are unable to accept requests to be registered for certain products only.

A typical Obsolescence Notification will consist of two documents - a summary letter and a full list of part numbers in a spreadsheet. You can see examples here:

The website will be updated with the date of obsolescence. You can see a typical example on the obsolete item M20-9701006.
